Owner reports
Selected complaints filed with NHTSA by 2017 Ford Expedition owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2017 Ford Expedition. The contact stated that while driving at approximately 45 MPH, the vehicle lost motive power and decelerated before the vehicle stalled. During the failure the message "Check Owner's Manual" was displayed. The vehicle was towed to the local dealer who diagnosed that the throttle body was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed that the VIN was not included in the Manufacturer's Extended Coverage for the throttle body failure. The failure mileage was 64,000.
Driving through a mile-long tunnel on an interstate highway (speed limit 55 mph), the vehicle ceased to respond to the gas pedal and would not accelerate or maintain speed. Attempted to shift gears but that produced no change - it was as if the transmission was stuck in neutral, but pushing the gas pedal did not increase the rpm. As we exited the tunnel at approximately 30 mph, the driver attempted to pull over and stop the vehicle, and found that the power assist for the brakes was not working, making stopping difficult - the driver had to push the brakes very hard, multiple times, to stop the car. We did contact 911 dispatch when we thought we were going to likely impede traffic, as the tunnel only had two lanes traveling the same direction. However, no intervention was required as we reached the end of the tunnel and were able to pull over before the call was completed. …
Throttle body and motor assembly failed at only 33,000 miles. Vehicle suddenly lost power and wrench light immediately illuminated on the dash. Vehicle had to be towed to local Ford dealership for repair. This created a very dangerous situation as the vehicle was currently being operated on a congested interstate on-ramp entering the highway with a very narrow shoulder / emergency lane. A vehicle accident & fatality could have easily occurred given this dangerous situation. Unfortunately this throttle body mechanical failure is a very common issue across many Ford vehicle platforms and the NHTSA has done the American consumer a disservice by allowing Ford to continue repairing these vehicles only when the throttle body unit fails. …
While driving my children, my 2017 Ford Expedition lost power and went into 'limp' mode (wrench appears on the dash) along with an incredibly rough idle. This is at least the 3rd time that this has happened (twice before replacing the current throttle bottle) and now. This is incredibly dangerous as the vehicle loses power and leaves my family and I at the mercy of other drivers around us. It has happened on a 6 lane freeway, a 2 lane highway, and, most recently, on a city street. After a very quick search of the internet, it is no secret that there are throttle body problems with 2017 Ford Expeditions. Ford is responsible for manufacturing a vehicle that is safe and free of mechanical defects. While some problems do arise unexpectedly, it is ignorant of Ford to continue to put passengers in harms way until an injury or death happens when there is a known issue.
Car stops accelerating at various speeds on numerous occasions, and cannot get vehicle to propel. No propulsion occurs. Must bring vehicle to complete stop, turn off, and turn back before it will accelerate. Large wrench appears on screen, but disappears after the car is restarted. Safety issue because you cannot maintain speed or accelerate, was almost rear-ended and created potential accident trying to pull vehicle over. Took two visits to the authorized dealer to diagnose the problem as their was no "code" apparent to dealer, and was almost rear ended in between those visits. Vehicle owner quickly googled problem and noticed that N. Carolina Consumers Council had successfully petitioned NHTSA for this issue on other Fords, but that recall appears not to have included these Expeditions. Dealer replaced the throttle body.
While travelling on highway uphill around 60 mph in heavy traffic, vehicle lost all power and went to idle. I had to maneuver 3 lanes to reach shoulder. Wrench icon showed on dash. Restarted engine and code cleared and had power again. It happened 4 more times over next 2 months then gave P2112 code. Research showed to replace throttle body which I did. Now doing some watchful waiting to see if it reoccurs. I believe this is a safety gap that requires a recall and a redesign of the logic to prevent the disabling the power train all the way back to idle.
Electronic throttle body will go into a limp mode and has no power to accelerate. This happens while driving down the street or highway and you might have enough power to pull to side of the road or street and not get run over. I have seen other reports of this and Ford extended their warranty on some vehicles to 10 years or 150,000 miles. These are mainly the eco boost motors. My vehicle has 88,000 miles and is regularly serviced. One occurrence was on a road under construction with no place to pull over quickly when this happened.
We were out of town driving to a baseball tournament going 80 miles an hour when the car completely lost power and a wrench came up. My husband barely coasted us to a shoulder. The car would not reset or restart unless it was in park. Happens twice. Took it for code read they said it is a throttle body issue but that instead of check engine light it shuts the whole car down until reset. Very scary on the interstate. Could have easily been in a bad collision.
while driving on the 58 freeway in the fast lane amongst semi trucks my expedition lost power and had no acceleration, i was forced to the left shoulder of the freeway putting my family and i in danger. while stopped i had no response from my gas peddle but the engine was still on and a wrench appeared on my dash lights. i turned off the car and when i restarted it the car worked again and the wrench was gone. very very very dangerous
I was driving the vehicle and it suddenly lost all engine power. The car was still on and running but slowed down to idle speed and was almost rear ended. I was barely able to get it over to the side street where I turned it off and then back on. And it ran like usual and I drove it back home, I was only a mile away. After further research it seems this is a known issue with the throttle body on these vehicles.
